Or5ap2 is an odorant receptor gene. Odorant receptors play a crucial role in detecting odor molecules and are also involved in non-olfactory functions. They may participate in signaling pathways related to chemosensation and potentially have an impact on various biological processes [1].

In a study on dwarf yellow-feathered broiler chickens, when fed with a basal diet supplemented with fermented bamboo powder (FPB), the expression of Or5ap2 was detected in the gizzard, proventriculus, and small intestine. Its expression was stronger in the small intestines compared to the gizzard and proventriculus. The FPB diet led to changes in growth performance, gut health, and the activation of odorant receptors, suggesting that Or5ap2 might be involved in the related physiological responses triggered by FPB [1].

In conclusion, Or5ap2, as an odorant receptor gene, shows responsive expression in the digestive organs of broiler chickens in response to a specific diet. Its role in growth performance and gut health in chickens indicates its potential importance in these biological processes, which may provide insights for understanding the underlying mechanisms in poultry health and growth regulation [1].
